• Q: How to remove the camshaft on 2002 Toyota MR2 Spyder?

  A: The process to remove the camshaft begins by taking out the engine unit plus generator and ignition coils and spark plugs and injectors and exhaust manifold through disconnecting heated oxygen sensor connectors and then discarding heated oxygen sensors before uninstalling 4 upper heat insulator bolts and 4 exhaust manifold stays bolts and the exhaust manifold with its attached gasket and 5 bolts. Next, disconnect the engine wire by detaching the heated oxygen sensor (bank 1 sensor 1) wire from the 2 wire brackets, the camshaft timing oil control valve connector, the crankshaft position sensor connector, the knock sensor connector, the oil pressure switch connector and wire, the camshaft position sensor connector, the ECT sensor connector, the throttle position sensor connector, the throttle control motor connector (SMT: 1), the accelerator position sensor connector (SMT: 2), the IAC valve connector, and the noise filter, then remove the 2 bolts and disconnect the 2 ground straps, followed by removing the 2 bolts and engine wire. Following this disconnect the PCV components by removing both PCV hoses and the PCV valve with its grommet. First disconnect the two water hoses from the throttle body and remove the two vacuum hoses from the intake manifold before you take out the four bolts and the two nuts and two wire brackets that allow for the removal of the intake manifold with throttle body assembly and its accompanying gasket. After the camshaft timing chain and timing sprocket and VVT sprocket removal process comes the removal of the camshaft timing oil control valve. To access camshaft components remove the 9 bearing caps together with the intake and exhaust camshafts after successive uniform bolt loosening of the 19 bearing cap bolts according to specified bolt sequences. The final step involves removing the cylinder head assembly after removing the water bypass pipe bolt from the cylinder head while applying a 10 mm bi-hexagon wrench for cyclic bolt loosening of the 10 cylinder head bolts in the correct order followed by removal of the 10 plate washers. Use a plastic prying tool to detach the cylinder head from the cylinder block while avoiding any surface damage to the contact areas. Remove the engine components by taking out the camshaft timing oil control valve filter as well as the camshaft position sensor and the ECT sensor.
